Abstract (en)
[origin: US2020347944A1] An actuated valve assembly includes a valve, an actuator, and a nut retention sleeve. The nut retention sleeve has a first bore portion sized to closely receive and rotate with a portion of a coupling member extending from the actuator and a second bore portion sized to closely receive and rotate with at least a portion of a stem nut assembled with a valve stem of the valve. The nut retention sleeve is slideable between a nut retaining position in which the second bore portion engages the stem nut to rotationally fix the stem nut with the coupling member, and a nut adjusting position in which the second bore portion is disengaged from the stem nut to permit rotation of the stem nut on the valve stem.
